SPECIFICATION forming part of Letters Patent N 0. 723,523, dated March24, 1903.

Application filed August 11,1902. Serial. No. 119,153. (No model.) I

To etZl whom, it may concern:

Be it known that I, PATRICK H. GARRITY, of Waterbury, in the county ofNew Haven and State of Connecticut, haveinvented a new and usefulImprovement in Screw-Drivers or Kindred Tools; and I do hereby declarethe following, when taken in connection with the accompanying drawingsand the letters of reference marked thereon, to be a full, clear, andexact description of the same, and which said drawings constitute partof this specification, and represent, in-- Figure 1, a perspective viewof a screwdriver or kindred tool constructed in accordance with myinvention; Fig. 2, a longitudinal sectional view-of thesame; Fig. 3, aper spective view of the shank of the tool detached.

This invention relates to an improvement in screw-drivers and kindredtools-such as screw-drivers, &c.and particularly to that class in whichthe shank of the tool extends entirely through the handle and so as tobe exposed at the outer end, the object of the invention being thesimple construction of a shank which is not liable to cause the handleto split and one which will permit of being struck, as with a hammer;and the invention consists in the construction as hereinafter described,and particularly recited in the claim.

As herein shown, the handle A may be of any approved design, formed witha longitudinal hole B, corresponding in diameter to the diameter of theshank C of a screw-driver or other similar tool. In the outer end of thehandle is an angular recess D, and the outer end of the shank is formedwith a head E, to which the recess D conforms and so that the head E maybe set into the handle flush with the outer end thereof. The inner endof the handle is provided with the usual ferrule F. If desired, andpreferably, a pin G will be employed which passes through the ferruleand through the shank of the tool, so as to'hold it in engagement withthe bandle. As herein shown, the head of the shank outer end inward andso that the head will be seated in the recess in the outer end of thehandle. After the handle is applied the end of the tool may be flattenedor otherwise formed as required, or a tool-point may be welded to theshank.

It will be understood from the foregoing that Iam aware that handles forscrew-drivers and kindred tools have been provided with longitudinalholes through which the shanks extend, that .the outer ends oftool-shanks have been made polygonal, and also that shanks have .beenprovided with wings 'at their outer ends and the handles with slots intowhich the said wings extend, and that shanks have been formed with headsto inclose the outer end of the handle, and therefore do not wish to beunderstood as claiming such as my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is p The herein-described screw-driver andkindred tool, comprising a shank having a substantially fiat, squarehead at its outer end,

and a handle having a longitudinal hole through which the shank extends,said han dle formed with a hollow square recess in its outer endcorresponding in shape to the shape of the head, and in depthcorresponding to the thickness of said head which it receives, and sothat the outer face of the head will stand flush with the outer end ofthe handle, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

PATRICK I-I. GARRITY.
